Go grab a torch.
Open both tailgates, and lift the little carpet flap thingy up from the lower tailgate, -handy if you have something to keep it up out of the way. (I used to have 2 rusty bolts in there until I replaced them with painted ones, but that's not what I'm talking about)
Switch the torch on, and take a look inside the square hole on the left (passenger) side of the car.
You will see a perforated steel grille in there, -not sure what it does, but it's probably rusty!

Thanks JLR, something else to worry about..... “If it ain’t broke, don’t fix it” -where’s the fun in that?

It's a plastic tailgate so they had to put some ferrous metal in there somewhere, and of course, leave it untreated....  Pete

It’s ok the sunroof drains will have totalled the car way before that causes a concern

Thanks for the heads up, another thing to obsessively check  Sold - Bell a 2015 MY16 Loire Blue Autobiography 4.4 SDV8

Thank God I have a “poverty spec” car, without roof drains or Dynamic Response corrosion to worry about, although my crankshaft is forged from high-density carotene, of course (yawn)
Said perforated steel bit isn’t in the lower tailgate itself, it’s in the bodyshell in front of the rear bumper, probs something to do with HVAC? I haven’t a clue, but my MY2017 has light surface rust in there already, and being perforated metal with a large surface area to volume ratio, older vehicles could be badly affected. I’ve sprayed some ACF50 in there for now.  “If it ain’t broke, don’t fix it” -where’s the fun in that?

Thanks for the heads up gremlin... Ill have a look at ours tomorrow

Yes, thanks Gremlin will check mine also. overfinch modified

May be not a rust trap, but if you want even more paranoia, pull out your front inner wing liners and check out the amount of leafs and stuff in there.

Oooooh, I love a bit of FFRR paranoia! The great thing with us paranoia-obsessed types is there is always something else to worry about you weren’t aware of, they just keep giving!
Out with family today so that one will have to wait

I have a vision of lots of FFRR owners up & down the country, trying to remember “now, where did I put that bl**dy torch?”  “If it ain’t broke, don’t fix it” -where’s the fun in that?

Just went to look at mine and found this....

So check that as well....  Pete

Same here. I've just been out to mine to check. I can't see any rectangular holes back into the body :-s

I have two galvanised bolts, each have a few spots of surface rust on them but by no means require replacement. Maybe a spray with some protection or a quick paint with some touch up paint to keep them looking good.

Can you take some pics of the place you are talking about Gremlin? Kev

Ah, sorry guys, I’ll try to take a picture, but big day tomorrow its the annual 4K service!

The hole is about 50mm square, and is readily visible on my MY 2017 model, the mesh is on a bulkhead maybe 60-70mm behind that, you will not see it without a strong torch in daylight, its pitch black in there! “If it ain’t broke, don’t fix it” -where’s the fun in that?
